COMBINED FEED 'WATER S IPHON AND TRAP.

SPEGIFIOATIONtbrming part of Letters Patent No. 699,331, dated May 6, 1902.

Application filed January 4, 1902. Serial No. 88,443. (No model.) I

To all whom] it rim/y concern:

Be it known that I, CHARLES Lnvs'rnon, a citizen of the United States, residing at Vicksburg, in the county of .WVarrenand State of- Mississippi, have invented a new and useful Combined Feed-Water Siphon and Trap, of.

- which the following is a specification My present invention relates to a novel feed-water siphon and trap'designed particularly for use in connection with the tendertanks of locomotives, and is an improvement in the art exemplified in my former patent, No. 568,620, dated September 29, 1896. The device illustrated in said patent inclndes a siphon the legs or branches of which are housed Within the tank in laterally-spaced relation. Said legs onbranches are connected by a return located above the tender, and one of them is rigidly connected to both the top and bottom walls of the tender. The return is provided with a lubricating and air cock for breaking the siphon'when the device is disconnected from the locomotive and for permitting the introduction of lubricating-oil, which is passed to the locomotive with the feed-water? One leg of the siphon has a flared-lower extremity-extended below the bottom of the tender and into a mudwell, thus locating the intake of the siphon at a point below the bottom of the tank to permit the complete evacuation of the latter. The object of my present invention is to simplify the construction described in my patent and to adapt the device for convenient application to locomotive-tanks of various constructions during the course of construction of the tank or subsequently.

A further object ofthe invention is to so relate the various parts of the siphon as to accommodate the relative movement of the top and bottom walls of the tank incident to contraction and expansion due to atmospheric.

changes or to the movement of the contained body of water. 7

Further objects of the invention are to facilitate the removal of eitherleg or branch of the siphon fOllPlllPOSGS of replacement or repair without in any manner interfering with the other leg or branch and to include as a feature of the device a trap containing means for effectually straining the water-before the latter passes to the interior of the siphon and constructed in a manner to insure the thorough cleansing of the trap of all accumulated sediment.

To the accomplishment of these objects without sacrificing any of the advantages of the earlier construction the invention comprehends as a preferred embodiment thereof that construction and arrangement hereinafter more fully described, illustrated in the accompanying drawings, and snccinctly defined in the appended claims.

In said drawings, Figure 1 is an elevation of a portion of a locomotive-tender equipped with my invention and having the side broken away. -Fig. 2 is a vertical sectional View through one leg of the tender-tank, showing the siphon and trap in diametrical section. Fig. 3 is an enlarged sectional view at right angles to the line of section in Fig. 2 and showing the trap and the lower portion of the siphon detached, and Fig. at is an enlarged sectional view on the line 4c 4 of Fig. 2. Like numerals of reference are employed to designate corresponding parts throughout the views.

As has been stated, my invention comprehoods the equipment of a Water-tank with improved means for effecting the withdrawal of water therefrom for the supply of anew gine-boilenbut is designed with special reference to locomotives, and in such connection is m on nted in and upon one leg or side branch of the tender-tank, (indicated in the drawings by the numeral 1.) To the bottom wall or' sheet 2 of the tank l is bolted or otherwise secured atrap 3, through which water from the interior of the tank is designed to pass into the lower open end of the ascending leg or branch 4 of a siphon 5, the major portion of which is housed within the tank and protected there- The lower end of the branch 4 of the siphon is slidably fitted within an annularguidc-fiange 6, upstanding from the top wall of the trap 3, and the upper end of said branch is screwed in or otherwise attachedto the lower end of a'ret'nrn or dome 7, bolted upon the top-wall or sheet 8 of the tank 1. The, mode of attachment of the dome 7 to the wall 8 of the tank and to the ascending, l gs of the siphon is immaterial, as stated; but by pref crence the lower edge of the dome is extend-.

ed through the wall 8 and has threaded engagement with the leg 4, as indicated at 9, and;

is provided with a horizontal annular flange l0, imposed upon the wall 8 and secured by bolts 11, as shown.

The descending leg or branch 12 of the siphon 5 is'located concentrically. within the ascending leg4 thereof and extends above the wall 8 of the tank and into the dome 7, where its upper end is guided between the inner ends of a series of guide-lugs 13, projectinginwardlyfrom thewallofthedome. Atitslower end the leg-12 is supported by the bottom .wall of the trap through the medium of a hosenipple 14, screwed into said wall and having threaded connection in turn with'the leg 12.

' they are relatively movable longitudinally to It will thus be observed that while the elements or legs of the siphon are properly related to permit the siphoning of the water fromthe tender-tank to the locomotive-boiler accommodate such slight approach or recession of the top and bottom walls of the tank as may be caused by the movement ofthe waterwithin the tank or by contraction and ezipansion incident to changes in atmospheric conditions. It will furthermore appear that the legs of the siphon may be removed for purposes of replacement or repair without in any manner affecting each other and without necessitating the detachment of the trap 3 from the tank. If it is desired to remove the ascending leg 4, it is simply necessary to release the dome from the wall-8, when, as will be evident-,the dome and said leg may-be litted out of the tank independently of the Similarly other 'elementsof the structure,

I, if it is desired 'to remove the descending leg the nipple 14 is unscrewed from the trap and the descending leg is withdrawn endwise,

- We now'come to a consideration of the novel trap comprehended by my invention and designed with special reference tothe straining of the water passing to the siphon and to the removal of the accumulated drainings by reverse circulation of the water through the sediment-chamber of saidtrap. The trap 3 isof generally oblong shape, with downwardly-converging end walls 15,'and is .formed at its upper edge with a horizontal bolt-flange 16, imposed against thelunde'r side I of thewall 2 and secured by bolts 17; as

shown; Within thetrap at a point below the lower end of the siphon leg 4 is disposed a horizontal 'pairtition 18, pierced by and con- I stitntingiii-guide for the inner or descending "leg'i12and also constituting a stop fora pair of fo'raminousstrainers or slidesl9 and 20,

sl-i'd'ably. received within suitable guides 21" in't se er i m m' sm r 18 to th top 'of-i;the' trap'. "Thjese strainers are designed to thoroughly cleanse the water as it passes through the trap to" the ascending leg of the siphon, and that part of the trap lying below and outside of the strainers will therefore constitutea sediment-chamber22, which may be cleared 'of the accumulated sediment by 1 the opening of an escape valve 23, controlling an'opening 24 in one of the walls 15, at or adjacent to the bottom of the tank.

To prevent accidental siphoning of water from the tank when the latter is not in communication with the engine-boiler, a lubricating and air cook 25 is provided upon the dome 7, and this cock may also be employedforthe introduction of lubricating-oil to the interior of the siphon, from whence it will pass tothe boiler with the feed-water. To the hosemipple 14 is attached a short section of flexible hose 26, which in practiceis coupled to a similar section in communication with the engine-boiler;

In operation,the feed-pipe of the locomotive being in communication with the siphon, the

injector is caused to exhaust the air from the siphon and to inaugurate a flow of water from by the opening of the cock 25to prevent the escape of water from the tank.

, If at any time it is desired to draw off the sediment from the sediment-chamber of the trap, it is simply necessary'to open the valve 23, and thus permit the water from the tank to flowfreely through the sediment-chamber for the purpose of flushing the same.

From the foregoing it will be observed that I have produced a simple, inexpensive, and edicient siphon and trap for feed-water tanks,

organized for convenient disassociation of the parts and for such relative movement thereof as may be necessary to prevent possible de rangement under the varying conditious of use; but while the present embodiment of the invention is thoughtat this time to'be'preferable I wish to reserve the right to effect such changes, modifications, and variations of the illustrated structure as may be suggested by within the scope of the appended claims.
